SfGantt - ResourceView - Error if Id's are based upon Guid

Hi,

I have been having multiple problems getting the SfGantt ResourceView to work.  I believe that there is an issue when using Guid Keys with the Task and Resource objects that feed into the grid.  I have also come up against an issue where an error is raised that seems to indicate that the Resource data type cannot be inferred.

The attached solution and video detail the various issues that I have been having and following is sample text of errors that have been raised.

I'd appreciate it if you can have a look and let me know if I have done anything wrong, or if there is a bug somewhere.
